Product Overview

Overview

The QSC SC-414 is a four-way screen-channel system, tri- or quad-amplified, combining the LF-4115 woofer cabinet with the MHV-1090 mid, high and very-high unit. The MHV-1090 uses a coaxial neodymium compression driver, a 3.5-inch HF diaphragm with a 1.75-inch VHF diaphragm, which QSC says gives wide dynamic range, extended high-frequency response and lower distortion, up to 20 kHz. Active crossovers sit at 280, 1,700 and 6,000 Hz.

What amplifier power is recommended?
For the SC-414: LF 800 W maximum, MF 800 W, HF 500 W and VHF 300 W maximum.
What are the impedances?
The LF-4115 is 4 ohms; the mid, HF and VHF sections are each 8 ohms.
Where does it sit in the range?

Can Corporate AV supply and install the QSC SC-414 in India, and how do I get a quote?
